How does Fit Pit work? Fit Pit is a natural deodorant. It prevents body odour caused by bacteria. Sweat does not usually have much of an odour unless we have eaten something particularly odorous! It is bacteria on the skin that causes odour. Fit Pit subtly alters your skin’s natural pH to prevent bacteria from thriving. The Coconut oil and Shea Butter, moisturise and soothe your skin. Unlike some deodorants Fit Pit doesn’t just mask a bad smell, it actually prevents it. And unlike antiperspirants Fit Pit doesn’t block your sweat glands, which means your body can still remove toxins, making it even healthier for you. The result is beautifully soft and healthy underarms. Skin Microbiome Our skin, just like our gut, is home to friendly bacteria which protect us from infection and inflammation. These bacteria thrive on our sweat particularly in dark moist areas, like our armpits, this can result in odour.
